In an alternative embodiment, a single end cap may include both the positive and negative terminals and the opposing end cap is simply a dummy which is not in electrical contact with the LED strip 5. Accordingly, the positive and negative terminals of LED strip 5 are in electrical contact with the respective positive and negative terminals of the aforedescribed dual-terminal end cap. In some embodiments, the two end caps are adapted to couple to existing standard fluorescent light sockets for adaptability and compatibility with common lighting systems. The size and shape of 9

11 the end caps shown in the figures should not be construed as limiting as the geometry of the end caps can be modified as desired to ensure compatibility with a wide variety of light sockets known in the art, including but limited to, high-output sockets used in signs and outline lighting systems. Accordingly, the term socket as used in this disclosure, should also not be construed as limiting, as the lighting system of the present invention can be configured to integrate with a variety of known socket configurations. Some embodiments of the present invention incorporate a specialized high-output end cap 15 as shown in FIGS. 3 a-3 e which is designed to fit new or existing high-output light sockets. In some embodiments, end cap 15 has three primary sections, a first cylindrical section 17, a second cylindrical section 19 coaxial to first section 17, and protrusion 21. In some embodiments, the first cylindrical section 17 has a larger diameter than the second cylindrical section 19 and protrusion 21 is dimensioned slightly smaller than the diameter of the second cylindrical section. Protrusion 21 has an open end 23 that is delimited by a curved cross section (where 23 points). In some embodiments, end cap 15 is a single uni-body structure made by known methods in the art such as extrusion or injection molding. However, in alternate embodiments, protrusion 21 may be removable. Accordingly, in one such embodiment, protrusion 21 may be mounted to or integrated with a disc-shaped base having, in some embodiments, substantially the same diameter as the second cylindrical section 19, such that the base functions as a cap for the remaining portion of end cap 15. As stated, end cap 15 is designed to function as a power terminal for some embodiments the present invention. Accordingly, FIG. 3 d is a cutaway view of the arrangement of and cap 15. Disposed within protrusion 21 are two pins 25 a and 25 b which are to be connected to the light socket of the given socket (not shown). In some embodiments, the pins are hollow cylinders capable of retaining the corresponding pins on the socket; in other embodiments, the pins may be solid 10

12 cylinders that are capable of being connected to hollow receiving pins on the socket. As shown in FIGS. 3 c and 3 d, the two pins 25 a and 25 b are spaced equidistantly across the elongated portion of protrusion 21.

Accordingly, cup 31 may have two apertures 33 a and 33 b which permit the proximal end of wiring 35 to pass through into housing 1. As such, the proximal end of wiring 35 is connected to pins 25 a and 25 b by soldering, crimping or other known methods. The distal end of wiring 35 may have a wiring harness 37 which is connected to and allows the transmission of power to LED strip 5 from the high-output sockets. Accordingly, LED strip 5 has a complementary wiring harness (not shown) which accordingly places end cap 15 into electrical contact with the LEDs 7. Col. 6, ll : With reference again to FIG. 5, disposed at either end of the housing 51 is a first end cap 550 that functions as a positive terminal (i.e. + lamp base); accordingly, disposed at the other end of the housing 51 is a second end cap 550 that functions as a negative terminal (i.e. lamp base) in one embodiment, the two end caps are adapted to couple to existing high-out fluorescent light sockets for adaptability and compatibility with common lighting systems. The 11

13 end caps are adapted to encase a plurality of electrical components defining an electrical terminal, described below. In an alternative embodiment, a single end cap 550 or 550 may include both the positive and negative terminals and the opposing end cap is simply a dummy which is not in electrical contact with the LEDs. Accordingly, the positive and negative terminals of the one or more LEDs are in electrical contact with the respective positive and negative terminals of the dualterminal end cap. Insulating stopper 556 (and 556 ) is disposed at the end of, and is received by, housing 51. Stopper 556 (and 556 ) may have a recess that is adapted to receive the end of divider 53, thus securing divider 53 within housing 51. In some embodiments, stopper 556 (and 556 ) is comprised of rubber or another like insulator. Terminal disc 555 (and 555 ) comprises a disc portion with power leads attached thereto. The leads are inserted through one or more apertures of stopper 556 (and 556 ) such that the disc portion of terminal disc 555 (and 555 ) rests against the end of stopper 556 (and 556 ). The leads are accordingly placed in electrical contact with strips 59 and/or 59.

17 a mechanical coupling element at each of said outwardly-facing sides of said end caps, said mechanical coupling element configured to engage a single electromechanical mount for a gas-discharge lamp, wherein said mechanical coupling element comprises electrically insulative material and does not retain any electrical conductors along or through said mechanical coupling element for powering the plurality of electric lamp units; and This limitation is met in light of the as described below. RetroLED contends that the term mechanical coupling element in the 835 Patent is governed by pre-aia 112, 6 as a means-plus-function term.if, however, the Court determines that the term mechanical coupling element is not governed by 112, 6, the nonetheless meet this limitation. For example, the Socarras Patent describes a device in which two end caps are adapted to couple to existing standard fluorescent light sockets for adaptability and compatibility with common lighting systems. (the Socarras Patent at col. 4, ll. 4-6.) The Socarras Provisional similarly describes two end caps that are adapted to couple to existing fluorescent light sockets (as shown) for adaptability and compatibility with common lighting systems. (the Socarras Provisional at 23.) These descriptions meet the requirements of the first portion of this limitation. Specifically, these two descriptions meet the following portion of the limitation: a mechanical coupling element at each of said outwardly-facing sides of said end caps, said mechanical coupling element configured to engage a single electro-mechanical mount for a gas-discharge lamp. With respect to the remainder of the language of this limitation, wherein said mechanical coupling element comprises electrically insulative material and does not retain any electrical conductors along or through said mechanical coupling element for powering the plurality of electric lamp units, this portion of the limitation is met by the in combination with United States Patent Publication No. 2009/ ( Huang ), United States Patent No. 8,419,223 ( Withers ), or Japanese Patent Publication No ( Royal Lighting ). As noted in the narrative to which this claim chart is an exhibit, Huang, Withers and Royal Lighting disclose lighting systems in which power for the disclosed lighting systems is provided in ways other than through the end caps and therefore, meet this limitation of claim 1 of the Breihof 835 Patent, requiring that the mechanical coupling element does not retain any electric conductors 16

18 along or through said mechanical coupling element for powering the plurality of electric lamp units. For example, the system in Huang is powered by an electrical cord separate and apart from the mounting pins and end caps as disclosed in Figures 2, 3, 6, and 7 and as described in paragraphs 8 and 19 of Huang. Similarly, Figures 1 and 2 of Royal Lighting show an electrical supply cord separate and apart from the mechanical coupling element while Figure 3 of Royal Lighting shows an electrical supply cord that is separate and apart from the mechanical coupling element of the lighting assembly and which is terminated with a plug for the power supply to supply power separate from the fluorescent mount by which the lighting assembly is supported. Finally, Figures 2, 3, and 4 of Withers show power application to the LED light tube through a path other than the mechanical coupling elements of the end caps and Fig. 5 of Withers explicitly shows a power strategy in which the power application and path is distant from the end caps themselves. For example, the Abstract of Withers states, Presented is an LED light tube in the general configuration of a prior art fluorescent tube. The LED light tube includes end caps with electrodes at each end, with the electrodes providing physical mounting structure to mount the LED light tube in an existing LED light fixture. The end caps of the LED light tube are not electrically active, but merely provide physical mounting structure to mount the LED light bulb in an existing fluorescent light fixture. This allows existing LED light fixtures to be utilized without replacement, by merely replacing the tubes and ballast with LED based equipment. (Withers at Abs.) 17

19 The include description of how to power the LED strips using a variety of options, including using the existing fluorescent lighting ballast, hardwired direct current or 120V alternating current with a rectifier to provide the direct current to the LED strips. (See, e.g., the Socarras Patent at col. 7, ll ; see also, e.g., the Socarras Provisional at 27.) Consequently, a person of ordinary skill in the art considering the problems of replacing fluorescent lighting with a more energy efficient and safer approach would be motivated to combine the teachings of the with those of Huang and/or Withers and/or Royal Lighting thus making this limitation obvious under 35 U.S.C Further and in the alternative, to the extent that it is not inherent that the mechanical coupling element comprises electrically insulative material, this limitation is rendered obvious by the in view of U.S. Pat. App. Pub. No. 2004/ filed September 25, 2003 and published April 1, 2004 to Cross et al. ( Cross ). Cross recites that an end cap is preferably fabricated from non-conductive materials. (Cross at 24.) Consequently, this limitation is available in the prior art of which the person of ordinary skill is deemed to have knowledge and, therefore, such a person in working to devise systems to replace fluorescent bulbs with lower power lighting assemblies would be motivate to combine the teachings of the and Cross thus rendering the purported invention of this limitation obvious in light of those references.

20 Col. 3, l. 57 col. 4, l. 59: Disposed at a first end of the housing 1 is a first end cap 15 that includes a positive electrical terminal (i.e. + lamp base); accordingly, disposed at the other end of the housing 1 is a second end cap 15 that includes a negative electrical terminal (i.e. lamp base). The positive terminal end cap is connected to the positive terminal of the LED strip 5 and the negative terminal end cap is connected to the negative terminal of the LED strip 5. In an alternative embodiment, a single end cap may include both the positive and negative terminals and the opposing end cap is simply a dummy which is not in electrical contact with the LED strip 5. Accordingly, the positive and negative terminals of LED strip 5 are in electrical contact with the respective positive and negative terminals of the aforedescribed dual-terminal end cap. In some embodiments, the two end caps are adapted to couple to existing standard fluorescent light sockets for adaptability and compatibility with common lighting systems. The size and shape of the end caps shown in the figures should not be construed as limiting as the geometry of the end caps can be modified as desired to ensure compatibility with a wide variety of light sockets known in the art, including but limited to, high-output sockets used in signs and outline lighting systems. Accordingly, the term socket as used in this disclosure, should also not be construed as limiting, as the lighting system of the present invention can be configured to integrate with a variety of known socket configurations. Some embodiments of the present invention incorporate a specialized high-output end cap 15 as shown in FIGS. 3 a-3 e which is designed to fit new or existing high-output light sockets. In some embodiments, end cap 15 has three primary sections, a first cylindrical section 17, a second cylindrical section 19coaxial to first section 17, and protrusion 21. In some embodiments, the first cylindrical section 17 has a larger diameter than the second cylindrical section 19 and protrusion 21 is dimensioned slightly smaller than the diameter of the second cylindrical section. Protrusion 21 has an open end 23 that is delimited by a curved cross section (where 23 points). In some embodiments, end cap 15is a single uni-body structure made by known methods in the art such as extrusion or injection molding. However, in alternate embodiments, protrusion 21 may be 19

21 removable. Accordingly, in one such embodiment, protrusion 21 may be mounted to or integrated with a disc-shaped base having, in some embodiments, substantially the same diameter as the second cylindrical section 19, such that the base functions as a cap for the remaining portion of end cap 15. As stated, end cap 15 is designed to function as a power terminal for some embodiments the present invention. Accordingly, FIG. 3 d is a cutaway view of the arrangement of and cap 15. Disposed within protrusion 21 are two pins 25 a and 25 b which are to be connected to the light socket of the given socket (not shown). In some embodiments, the pins are hollow cylinders capable of retaining the corresponding pins on the socket; in other embodiments, the pins may be solid cylinders that are capable of being connected to hollow receiving pins on the socket. As shown in FIGS. 3 c and 3 d, the two pins 25 a and 25 b are spaced equidistantly across the elongated portion of protrusion 21. In some embodiments, pins 25 a and 25 b are recessed with respect the top-most boundary of protrusion 21 such that the pins are not susceptible to damage or breakage during handling or storage of the present invention. Also shown in FIG. 3 c are contacts 27 a and 27 b which, in some embodiments, are located to the inside of pins 25 a and 25 b, respectively. Contacts 27 a and 27 b may comprise metal tangs which are curved over and retained by supporting structure of end cap 15, respectively. It is understood that, for the purposes of this disclosure, the pin/contact arrangement results in an electrical terminal that is capable of receiving electrical power from a power source, as described below. Col. 7, ll : As is well known in the art, standard fluorescent lighting systems are typically powered by a ballast system in order to regulate the flow of electrical power to the fluorescent bulbs. However, because LEDs operate under different conditions than a fluorescent bulb (typically, LEDs run on direct current (DC)), ballast power generally will not be needed. Accordingly, some embodiments of the present invention may also comprise a power source such as a power supply which is used as a transformer/rectifier in order to properly power the LED lighting system of the present invention. In some embodiments, it is intended that the power supply 20

22 replace the ballast systems in traditional fluorescent lighting systems. In other embodiments, the light sockets themselves may be hardwired to a power grid (i.e. a building's electrical infrastructure) such that it will provide optimum voltage to the LED lighting system of the present invention. Accordingly, the positive and negative terminals of the power supply are connected to the respective positive and negative terminals of the powered socket system. Power is supplied to the terminals, through to the end caps, and in turn, to the appropriate terminals on the LED strip. In some embodiments, power supply may be capable of accepting and converting 120V AC power (the input voltage ) to the appropriate DC power. In other embodiments, the acceptable input voltage may range from 50V AC up to 270V AC, depending on the particular application. In yet other embodiments, a 24 Volt power supply may be used wherein the power supply includes a transformer/rectifier in order to properly power the LED strip. In some embodiments, the 24 Volt power supply is intended to replace high-out ballast that are typically used for high-output sign lamps. For the Socarras Provisional: Figures: 3a, 3b, 3c, 3d, and 4. 23: Disposed at a first end of the elongated housing is a first end cap 15 that functions as a positive terminal (i.e. "'+" lamp base); accordingly, disposed at the other end of the elongated housing is a second end cap 15 that functions as a negative terminal (i.e. "-" lamp base). The positive terminal end cap is connected to the positive terminal of the LED strip and the negative terminal end cap is connected to the negative terminal of the LED strip. In one embodiment, the two end caps are adapted to couple to existing fluorescent light sockets (as shown) for adaptability and compatibility with common lighting systems. The size and shape of the end caps shown in the figures should not be construed as limited, In some embodiments, the end caps may be glued or epoxyed to the ends of housing 1. 21

End cap 15 has three primary sections, a first cylindrical section 17, a second cylindrical section 19 coaxial to first section 17, and protrusion 21. In some embodiments, the first cylindrical section 17 has a larger diameter than the second cylindrical section 19 and protrusion 21 is dimensioned slightly smaller than the diameter of the second cylindrical section. Protrusion 21 has an open end 23 that is delimited by a curved cross section (where 23 points). In some embodiments, end cap 15 is a single "uni-body" structure made by known methods in the art such as extrusion or injection molding. However, in alternate embodiments, protrusion 21 may be removable. Accordingly, in one such embodiment, protrusion 21 may be mounted to or integrated with a disc-shaped base (not shown) having substantially the same diameter as the second cylindrical section 19 such that the base functions as a "cap" for the remaining portion of end cap : As stated, end cap 15 is designed to function has a power terminal for some embodiments the present invention. Accordingly, with reference to figure 3d, shown is a cutaway view of the socket arrangement of end cap 15. Disposed within protrusion 21 are two pins 25a and 25b which are to be connected to the light socket of the given fixture (not shown). In some embodiments, the pins are hollow cylinders capable of retaining the corresponding pins on the fixture; in other embodiments, the pins may be solid cylinders that are capable of being connected to hollow receiving pins on the fixture. As shown, the two pins 25a and 25b are spaced equidistantly across the elongated portion of protrusion 21. In some embodiments, pins 25a and 25b are recessed with respect the top-most boundary of protrusion 21 such that the pins are not susceptible to damage or breakage during handling or storage of the present invention. Also shown are contacts 27a and 27b which, in some embodiments, are located to the inside of pins 25a and 25b, respectively. As show in figure 4, contacts 27a and 27b may comprise metal "tangs" which are curved and retained by supports 29a and 29b, respectively. It is understood that, for the purposes of this disclosure, the 22

24 pin/contact arrangement results in an electrical terminal that is capable of receiving electrical power from a power source, as described below. 23
